Ways To Defrost Your Mashed Potatoes
In case you’ve kept your mashed potatoes in the freezer for longer storage, then it’s important to properly thaw them before reheating. Properly defrosting mashed potatoes is crucial to ensure that they are heated evenly and have a desirable texture.
There are a few ways to defrost your mashed potatoes, depending on how much time you have. The most reliable way is to thaw them in the fridge overnight, but if you’re in a hurry, you can also use a microwave or stovetop.
For microwave defrosting, transfer the mashed potatoes into a microwave-safe dish and heat in short increments, stirring frequently until they have thawed.
For stovetop defrosting, transfer the mashed potatoes into a pot and heat gently over low heat while stirring occasionally.
Just remember to avoid reheating frozen mashed potatoes more than once to maintain their texture and flavor.
